1/4 inch Galvanized Iron 90 Degree Elbow Female x Female

1/4 inch Galvanized Malleable Iron 90° Elbow – Threaded Fitting for Directional Flow in Piping Systems

The 1/4 inch galvanized 90-degree elbow is a malleable iron fitting engineered to facilitate right-angle directional changes in threaded pipe systems. It is commonly used in air, water, gas, and oil lines where corrosion resistance and mechanical strength are required. Manufactured in accordance with ASTM A197 and galvanized to ASTM A153 standards, this fitting provides long-term durability in interior and exterior installations.

With NPT (National Pipe Thread) taper threads on both ends, this elbow fitting allows for easy assembly with compatible 1/4 inch male-threaded steel or iron pipe. The hot-dip galvanized coating offers superior protection against corrosion, making it ideal for high-humidity or outdoor applications. Malleable iron construction supports robust handling and working pressures in both commercial and industrial systems.

Key Technical Features

• ✅ Material: ASTM A197 malleable cast iron with hot-dip galvanized finish
• ✅ Thread Standard: ANSI/ASME B1.20.1 NPT female threads
• ✅ Working Pressure: Rated for up to 300 PSI non-shock (water, oil, air); consult manufacturer for gas service
• ✅ Temperature Range: Up to 150°F for water/oil/air systems
• ✅ Compliance: Meets or exceeds ASTM A197, ANSI/ASME B16.3, and ASTM A153 for galvanized coatings

Recommended Applications

This 90° elbow is used in threaded piping networks for directional flow changes. Typical uses include:

• Plumbing lines requiring 90° turns in compact spaces
• Compressed air systems in mechanical and fabrication shops
• Hydronic heating systems with threaded steel piping
• Gas distribution where code permits threaded malleable iron

Installation Guidance

Use a compatible thread sealant or PTFE tape on all male NPT threads to ensure leak resistance. Over-torquing may lead to thread deformation; follow torque guidelines based on piping material and diameter. Tighten using a pipe wrench on the wrench flats provided, taking care not to damage the galvanized coating. For gas or critical system applications, pressure testing is recommended after installation.

Did You Know?

Galvanized malleable iron is preferred over plain cast iron in corrosive environments due to its protective zinc layer, which acts as a sacrificial anode. This increases service life, particularly in exposed or high-moisture installations.

Specify the 1/4 inch galvanized 90° elbow when reliability, pressure tolerance, and corrosion protection are required. Designed to meet code requirements and field-tested in diverse applications, this fitting ensures solid performance in demanding environments.
